V 11. Screwed on the shaft there is a nut 12.

My object is to produce a winding means The nut has a round-extension 13 that is for this and other class of springs so conreceived in the socket 8, and that contacts structed as to permit of the handle portion with the spring 11. Also screwed on the 65 yielding on the stem or shaft portion when threaded end of the shaft and. contacting the spring has become fully wound to avoid with the nut 12 there is a winged nut 14.
